For an understanding of plain Japanese, a certain level of Japanese skills is required. However, rewriting to plain Japanese requires relatively high cost, such as use of an intelligible word, paraphrasing and so on. There is a method which show native information by machine translation to communicate with foreign residents. Japanese skills acquisition is not required when machine translation performs information presentation by a native language. We think that this method has little load for a foreign resident in Japan. However, when translation accuracy is not good, this method may cause big load for an understanding of a meaning of a sentence, or you may be unable to understand a sentence at all. We investigated the ease of understanding between plain Japanese and machine translation (Chinese) at Japanese beginners who are Chinese a native language. We carried out the experiment: a description experiment of the contents which can be read in a text. As a result, we obtained following findings. (1) Machine translation can be easier to understand the meaning of a sentence than plain Japanese for Japanese beginners. (2) The length of a sentence, in the easy Japanese sentence (an average of 45.0 characters) and in machine translation sentence (an average of 33.0 characters), has not influenced an understanding of a meaning of a sentence. (3) The accuracy of a machine translation sentence influences an understanding of a meaning of a sentence. However, we found that the sentence with low evaluation of accuracy has also read most meanings about the sentence of about 60 %.}, title = {やさしい日本語文と機械翻訳文の理解のしやすさに対する影響要因の分析}, year = {2013} }
